The value of the expression is -27.

What is an expression?

In mathematics, an expression is a combination of numbers, symbols, and operators that represents a mathematical quantity or a mathematical relationship between quantities. Expressions can be simple or complex, and they can include variables, constants, functions, and other mathematical objects.

First, we can simplify the expression inside the parentheses:

-(-4)(-6) - 3/5 (10+15) = 24 - 3/5 (25)

Next, we can simplify the fraction:

24 - 3/5 (25) = 24 - 15 = 9

So the expression simplifies to:

-9 ÷ 1/3

-9 x 3/1 = -27

Therefore, the value of the expression is -27.

Step-by-step explanation:

Answer:

\(37d + 0.20m \le 95\)

Step-by-step explanation:

Given

\(Cost = 95\) --- not more than

\(daily = 37\)

\(mile = 0.20\)

Required

Represent as an inequality

Let the number of days be d and the number of miles be m.

So, we have:

37d for d days and 0.20m for miles

Not more than means \(\le\)

So, the inequality is: \(37d + 0.20m \le 95\)

The probability that at most 24 heads occur 0.00000077.

We can model the number of heads as a binomial random variable with n = 25 and p = 0.5.

We want to find the probability that at most 24 heads occur, which is the same as finding the probability that 0, 1, 2, ..., or 24 heads occur.

Using a binomial probability table or calculator, we can find the individual probabilities for each outcome and then add them up:

P(X ≤ 24) = P(X = 0) + P(X = 1) + ... + P(X = 24)

= 0.00000003 + 0.00000075 + 0.00001216 + 0.00013733 + 0.00109392 + 0.00663471 + 0.03192139 + 0.11641502 + 0.30035400 + 0.50000000

= 0.95566955

Therefore, the answer is (e) 0.99999923 (rounded to 8 decimal places).

One of three different floors each day during a 4-day work week in 12 different ways, can be assigned to the nursing student.

To find the number of ways a nursing student can be assigned to one of three different floors each day during a 4-day work week, we need to use the multiplication principle of counting.

First, we need to determine the number of options the nursing student has for each day. Since she can be assigned to one of three different floors, she has 3 options each day.

To find the total number of ways she can be assigned over the 4-day work week, we multiply the number of options she has for each day by the number of days in the week:

3 options per day x 4 days = 12 total ways

Therefore, the nursing student can be assigned to one of three different floors each day during a 4-day work week in 12 different ways.

Answer:

1658.3

Step-by-step explanation:

the perimeter of a semi - circle is simply half the circumference of a circle.

that is ;

1 / 2 ( pi ( r² ) )

where;

pi = 3.14 ( this is a constant that should be known and also equals 22 / 7 )

r = radius ( or half a diameter )

in our question, we are given a diameter with no radius

this means that we will have to halve the diameter to give us our radius

that is;

d = 65cm

r = 65 / 2

r = 32.5

so, using our formula;

1 / 2 ( 3.14 ( 32.5² ) )

1 / 2 ( 3.14 ( 1056.26 ) )

1 / 2 ( 3316.65 )

1658.3125

The equation of the quadratic function f whose graph is shown below is x² + 6.1x + 8.2

Find the diagram attached.

First, we need to get the zeros of the required function. The point where the curve cuts the x-axis is the zeros.

According to the graph, the curve cuts the x-axis at x = -2 and x = -4.1

The required factors will be (x+2) and (x+4.1)

Taking the product of the factors

f(x) = (x+2)(x+4.1)

f(x) = x²+4.1x+2x +8.2

f(x) = x² + 6.1x + 8.2

Hence the equation of the quadratic function f whose graph is shown below is x² + 6.1x + 8.2

Answer:

is finding the square root

The inverse operation of squaring a number is finding the square root of that number. The square root of a number "x" is the value that, when squared, gives the original number.

When a number is squared, it is multiplied by itself. For example, squaring the number 4 gives 4^2 = 16.

The inverse operation undoes the effect of squaring and returns you to the original number. In this case, finding the square root of a number is the inverse operation of squaring.

The square root of a number "x" is a value that, when squared, gives the original number. It is denoted by the symbol √x.

For example, if you have the number 25 and you want to find its square root, you calculate:

√25 = 5

5 is the square root of 25 because when you square 5 (5^2), you get 25.

The inverse operation of squaring a number is finding the square root of that number. The square root of a number "x" is the value that, when squared, gives the original number. The concept of square root and squaring are inverse operations that are used in various mathematical calculations and problem-solving.

The homework for the last week of school would take 6 seconds mod 11.

The problem can be modeled using a geometric sequence, where the first term is 1 and the common ratio is 2 since the amount of homework doubles each week. The nth term of the sequence can be found using the formula:

a_n = a_1 *\(r^{(n-1)\)

where a_1 = 1 and r = 2. We want to find the value of the 32nd term or a_32. Plugging in the values, we get:

a_32 = 1 * \(2^{(32-1)\) =\(2^{31\)

We can simplify this value by taking it mod 11. Since \(2^{10\) = 1024, which is congruent to 1 mod 11 (i.e., 1024 mod 11 = 1), we can use this fact to simplify \(2^{31\) as follows:

\(2^{31\)= \(2^{30\) * 2 = \((2^{10})^3\) * 2 = 1³ * 2 = 2

Therefore, the amount of homework for the last week of school would take 2 seconds, which is equivalent to 6 seconds mod 11 (i.e., 2 mod 11 = 6).

Dr. Ramirez has chosen a longitudinal research design for her study with adolescent participants. In this design, she will measure the number of hours of sleep the participants get each night over a period of 8 years. The participants in this study are a group of 13-year-olds who were all born in the same month.

The longitudinal design involves studying the same group of individuals over an extended period of time to track changes and developmental patterns. In this case, Dr. Ramirez will meet with the participants every 6 months for 8 years to collect data on their sleep duration. This design allows her to observe how sleep patterns change throughout the period of adolescent development.

By choosing a group of 13-year-olds born in the same month, Dr. Ramirez ensures that the participants are similar in terms of their age and potential developmental factors. This helps to minimize the impact of age-related differences on the sleep patterns being measured.Overall, the longitudinal research design allows Dr. Ramirez to examine how sleep duration changes over time in a specific group of adolescents, providing valuable insights into the developmental trajectory of sleep patterns during adolescence.

Answer :not fully correct

cStep-by-step explanation:

1.)  Probabilities range from 0 to 1, denoting impossibility and certainty, respectively.

2.) The sum of probabilities of all possible outcomes is equal to 1.

1.) Individual probabilities will always have values between 0 and 1. This property is known as the "probability bound." Probability is a measure of uncertainty or likelihood, and it is represented as a value between 0 and 1, inclusive.

A probability of 0 indicates impossibility or no chance of an event occurring, while a probability of 1 represents certainty or a guaranteed outcome.

Any probability value between 0 and 1 signifies varying degrees of likelihood, with values closer to 0 indicating lower chances and values closer to 1 indicating higher chances. In simple terms, probabilities cannot be negative or greater than 1.

2.) The sum of the probabilities of all individual outcomes must equal 1. This principle is known as the "probability mass" or the "law of total probability." When considering a set of mutually exclusive and exhaustive events, the sum of their individual probabilities must add up to 1.

Mutually exclusive events are events that cannot occur simultaneously, while exhaustive events are events that cover all possible outcomes. This property ensures that the total probability accounts for all possible outcomes and leaves no room for uncertainty or unaccounted possibilities.
